Question

What type of joint allows twisting, turning, and sliding in the vertebrae?

Answer 1

Gliding joints.

Explanation:

There are six broad types of joints (articulations) with different degrees of flexibility and movement. Based on the amount of movement they allow they are grouped into:
1. Immovable Joints - no active movement possible.
2. Slightly Movable Joints - limited movement possible.
3. Freely Movable Joints - greater degrees of movement possible.

Freely Movable Joints are further subdivided into `6` sub-categories, of which Gliding Joints is one of them.

Gliding Joints have nearly flat or slightly curved articulating surfaces that allow twisting, turning, and sliding movements. Examples of such joints are some wrist and ankle bones, and those between adjacent vertebrae.
